Sequence of work
"Daily Maintenance"
1. Check the coolant level on a cold engine - the cooling system is not under pressure.
Pic. 4.43. Expansion tank: 1 - safety ring; 2 - gasket; 3 – sensor; 4 - float with lever
2. With a cold engine, the level should reach the dividing fold between the upper and lower parts of the tank (pic. 4.43). In this case, the float of the sensor occupies the upper position. On a hot engine, the fluid level rises higher.
Pic. 4.44. Adding coolant up to the mark (arrows)
3. To add fluid, open the filler neck (pic. 4.44). With a hot engine, grab the cap with a thick rag and open it slowly to equalize the pressure of the hot fluid with the outside. If you open the lid too quickly, pressurized fluid will be thrown out of the neck.
4. Do not add liquid above the dividing fold of the expansion tank, the coolant will expand when heated and the excess will be thrown out.
